Comments: Hi,
What is the difference between Valvoline XLD Classic 20w50 and Valvoline XLD Premium 20w50?
You dont seem to list Classic on your website, and I cant find much Info on the Premium.
I'm trying to find out what sort of additives are in the 2 so I can decide which would be best to use in my classic minis (1975) engine.
Thanks
This is the response I got a few minutes ago

Hi Matt,
XLD Classic is no longer in production. We stopped it early this year.
The XLD Premium has replaced the Classic, you can use the Premium, no worries at all.
The Premium is only a slight up grade of the old Classic.
The Classic was an API SG/CD, the Premium is API SJ/CF, meaning its backward compatible.
It still has the same zinc ( ZDDP ) as the Classic, which is what you need. Its still a full mineral oil.
The upgrade of the Classic to the Premium was to make it compatible with more naturally aspirated petrol and diesel motors.
Your Mini will love you for it.
You can still find SG sped'd 20W50 oils still at most Supermarkets, IGA, COLES, WOOLIES, in their home
brand labels if you really want to have an SG.
These oils are of the same quality as the Classic.
If you want clarification you can call me on the toll free number below.
I use the Premium in our Moke and she loves it!!!!
